I swear to god...
Thank you for volunteering for the ignore list. Now I'll move on.
Alternative crackpot theory!
The guy played 40 hours, right? And thinks he's at the end of the game, right?
This, from the afrojack trailer, looks like it may well be the section he's referring to:
Which, to me, looks a little bit like he's on his way back to Insomnia to reclaim his throne.
So, I've been of the mind that the game does NOT end with you reclaiming the throne. IMO, there have been many clues to this effect, though nothing concrete. Generally, these things start with a more "local" goal and expand to, basically you killing God of some kind by the end of it. My guess? The preview is only on the first half or 2/3 of the game, and this leads to the transition from young to old Noctis and crew.
